What Foods Can I Eat for a Low Sodium Diet?

Sodium, or salt, is an electrolyte your body needs to function properly. However, almost all Americans eat too much sodium in their diets. The recommended upper amount of sodium in a normal healthy diet is 2300 milligrams, which is about the amount in one teaspoon of salt. While almost everyone should eat foods that are lower in sodium, for some people it's especially important. If you have medical issues such as high blood pressure, kidney disease, or heart problems, you may benefit even more from a low-sodium diet.

A low-sodium diet may have many benefits. Reduced salt may:

• Lower blood pressure in people with high or borderline blood pressure
• Prevent fluid collection in the lower legs or abdomen
• Prevent high blood pressure and swelling, called volume overload, in people with chronic kidney disease and heart failure
• Lower blood pressure slightly in people with normal blood pressure, which lowers the risk of heart disease
• Help blood pressure medicines work more effectively
• Help with weight loss
• Reduce the risk of dying from stroke
• Reverse heart enlargement
• Reduce the risk of kidney stones
• Reduce the risk of osteoporosis, which is thinning bones

While most people shouldn't eat more than 2300 milligrams of sodium per day, people on a low-sodium diet should aim for less than 2000 milligrams daily or the guidelines provided by your doctor. Your body only needs about one-fourth of a teaspoon daily. The average American eats five or more teaspoons daily. Even if you resist the salt shaker at meals, many prepared and processed foods contain a large amount of sodium. 

Here are some general guidelines for avoiding high-salt foods: 

• Eat meals cooked at home since they generally have less salt than prepared foods. 
• Choose fresh food instead of processed whenever you can.
• Watch sodium levels in over-the-counter medicines such as Alka Seltzer.
• Don't use softened water to cook with or drink since it has added salt.
• Use non-salt seasonings on your food such as vinegar, lemon, garlic, ginger, and other herbs and spices.
• Read the labels on packaged foods. Foods that have less than 140 milligrams of sodium per serving are considered low in sodium. 
• Avoid foods that have over 400 milligrams of sodium per serving. 

You can't always tell by taste which foods are lower in sodium. Some foods have a lot of hidden sodium. Here are some low-salt foods that can be a part of your healthy diet.
